Breast overflow is yellow, mostly due to infection in the ducts of the breast, resulting in increased secretions. Breast overflow can be treated with oral antibiotics, such as penicillin or cephalosporin antibiotics, while paying attention to breast cleanliness and hygiene, and also local heat compresses to promote local blood circulation and improve symptoms. If the effect of oral medication is not obvious, breast ductoscopy can be done to determine the situation of breast overflow, and if necessary, it can be combined with the treatment of lavage in the breast ducts. If the breast overflow is bloody overflow, malignant breast tumors need to be ruled out. Ultrasound examination can be done or biopsies can be taken and sent to pathology to confirm the diagnosis of malignant tumors, and then chemotherapy medication can be given according to the specific type of pathology in a timely manner. Papillary overflow can also be seen in intraductal papillomas, which require surgical removal if drug therapy is not effective. Nipple overflow medication needs to be judged according to the nature of the specific cause of the overflow.
